摘要：
A prosthetic hip implant system includes a prosthetic femoral component having a stem portion, a neck portion coupled to the stem portion and a part-spherical head coupled to the neck portion. An acetabular component is provided which has a housing, the housing having a part-spherical inner surface having an open end with a circumferential rim portion. The rim portion has a circumferential radially inwardly extending flange. A bearing element is mounted within the housing and has a part--spherical first outer surface region engaging the part-spherical inner surface of the housing. The part-spherical first outer surface region extends at a first radius from a center. The bearing element has a second part-spherical outer surface region extending a distance from the center less than the first radius to form a stop surface for contacting the rim.
